The MuLan experiment seeks to measure the muon lifetime to 1 ppm. To achieve this level of precision a multitude of systematic errors must be investigated. Analysis of the 2004 data set has been completed, resu
3 Systematic error Systematic error cannot be treated by the methods outlined above. If the result is too great by 1% because of some inherent deficiency in the experiment, endless repetition will make no difference. Systematic error can be detected by performing a second measurement where there ...
A good negative control experiment consists in evaluating pairs of responses that unquestionably result from the same receptor-transducer interaction. Any bias detected in such cases represents "non-statistical noise" (i.e. a statistically significant false positive result), because the methods are ...
(Fig.1a). Each experiment was performed in technical replicates across centers with a target of 3,000 cells per sample to recover all major PBMC cell types, such as T and B cell subtypes, natural killer (NK) cells, monocytes and dendritic cells (DCs). In total, we generated 47 datasets...
During a series of measurements of the acceleration due to gravity using a simple pendulum, you observe that the measurements vary slightly around the accepted value each time you perform the experiment. What type of error is this, and how can it be minimized? Click here to show/hide answer...
An experiment that can probe, directly, whether a sta- tistically meaningful change in the necessarily stochastic position of a gene relative to the NE causes a systematic, statistically meaningful change in the gene expression (the structure → function causality) would be most appropriate, but ...
For studies with newborns and animals, we assessed the performance bias as medium since neither newborns or animals are likely to be aware of being part of an experiment or specific group. An overview of the results is presented in Supplementary Fig. 21, and the precise assessment for each ...
in deeply sequenced datasets for HFFc6 cells (Fig.5a). We found that they were proportional to each other at a factor of 2 in the FA–DpnII experiment, but not in the experiments with improved loop detection (FA + DSG–DpnII and FA + DSG–MNase). This suggests that many of...
In Experiment 1, it could be argued that the coding of a visual target in the head-fixed condition was actually interfered with by the awkward position the eyes had to assume when fixing on targets in Sections 1 and 3 of the working space. Therefore, in this study the presentation of ...
The two main types of measurement error are random error and systematic error. Random error causes one measurement to differ slightly from the next. It comes from unpredictable changes during an experiment. Systematic error always affects measurements by the same amount or proportion, provided that a...
